Two different simple random samples are drawn from two different populations. The first sample consists of 20 people with 9 having a common attribute. The second sample consists of 2000 people with 1440 of them having the same common attribute. Compare the results from a hypothesis test of p 1equalsp 2 (with a 0.01 significance level) and a 99% confidence interval estimate of p 1minusp 2.
Identify the test statistic.
Identify the critical value(s).

Joe is interested in driving a new SUV for three years. There are two options—purchasing or leasing. A local car dealer quoted him a leasing deal of $2000 down and $299 a month for 36 months. Alternative he can purchase the vehicle at $22,000 and sell the SUV in 36 months at 60% of the purchase price. Joe would like to get your help in deciding which option is best. Assume that the interest rate is 6% (APR compounded monthly).

The engineers working on the tower were very interested in
how
much the tower would lean if no corrective action was taken.
Use
the OLS estimation to predict the tower's lean in the year 2000
if
no corrective action had been taken.

A medical stats class is interested in the mean pulse rate of "senior citizens". How many individuals are required to estimate the pulse rate with 99% confidence that the mean is within 2 beats per minute of the population mean. Based on 2000 NIH data, assume a std deviation of 12.5 beats per minute.
b) Recent data suggests the std deviation is closer to 17 bpm. How does a 99% CI with this std deviation compare to (a) above?
